Manju(Japanese sweet bean-filled pastries), adapted from this recipe. These are supposed to look like chestnuts, but a lack of egg wash resulted in a lack of browning.

Egg-shaped manju.

A peek at the homemade shiro-an filling for the manju.

None are specifically tied to new year festivities, but I did keep traditional, symbolic elements in mind (e.g., roundness of each item signifying wealth, clementines representing luck, white rice ushering in a clean start). Even if that is a bit of a stretch, one can't really go wrong with just a little sweetness to start the year, right?
